glucose is transported back into the bloodstream
red and white blood cells
protein
Protein
because glucose and other nutrients are small to filtrate through the filtration membrane and glucose is essential to be in the filtration membrane.
. Since proteins are very large molecules (macromolecules), they are not normally present in measurable amounts in the glomerular filtrate or in the urine. The detection of protein in urine, called proteinuria may indicate that the permeabilityof the glomerulus is abnormally increased. This may be caused by renal infections or it may be caused by other diseases that have secondarily affected the kidneys such as diabetes mellitus, jaundice, or hyperthyroidism.
Basically blood plasma minus proteins. The glomeruli can filter out most serum proteins, but lets a few small ones through (I think the cutoff is like 25kD). Some albumin does manage to get through, this is recovered in the proximal tubule.
Ions and nutrients
- It contains all plasma components except protein. - It loses water, nutrients, and essential ions to become urine.
